Pheasant Use And Waterfowl Production On State And Private Lands, Charles R. Elliott
Electronic Theses and Dissertations
Ring-necked pheasant (Phasianus colchicus) use on state-owned game production areas was compared to that on privately-owned areas in east-central South Dakota. Four 80-acre and four 160-acre tracts of state lands were paired with private areas of the same size having the same amount of wetland and were selected from aerial photographs taken before the purchase of the state-owned areas. None of four nests were successful on private areas in 1968 and three of five nests were successful on game production areas. In 1969 three of 19 nests were successful on private areas and 10 of 21 nests were successful on …

Electronic Theses and Dissertations
Gout is one of the earliest disease entities to be described in medical writings. Hippocrates noted familial distribution patterns and described its classic symptomatology in the 5th century B.C. Empirical treatment employing colchicine was advocated by Alexander of Tralles in the 5th century A.D. A better understanding of the complex association between clinical manifestations of gout and uric acid, carbohydrate and lipid metabolism has made rational treatment possible only very recently. Ample experimental and clinical data now available show a definite association between disorders of purine metabolism resulting in hyperuricemia and frequent concomitant hyperlipidemia. A high incidence of both …
Student Instruction Manual For Black And White Film Processing And Printing, Stephen Michael Delay
Student Instruction Manual For Black And White Film Processing And Printing, Stephen Michael Delay
Electronic Theses and Dissertations
For most subject matter the ideal classroom situation would allow a one-to-one relationship between instructor and student. In teaching basic photography this is especially true because of the great number of steps involved in producing a finished photograph and because each step must be done correctly to achieve good results. Time won't permit the instructor to effectively follow each student through all the steps involved, and, ideally the student should be allowed to work at his or her own speed. The one-to-one relationship therefore, isn't possible in most photography classes and, for that reason, something is needed to take the …

Physical Conditioning And Ammonium Carbonate Affecting Blood Ammonium And Swimming Performance Of Dogs, Larry Alan Bjurstrom
Electronic Theses and Dissertations
Ammonia is produced by the working muscle of exercising mammals and cellular metabolic process of resting mammals. Normally relatively minute blood ammonium-nitrogen (BAN) levels are present because mammals have efficient systems for excreting ammonia or converting it to non-toxic end products. Impaired or inadequate detoxification process allow elevated BAN levels with excessive ammonia production. Above normal BAN levels produce deleterious effects which are well known to many research fields. When impaired or inadequate detoxification process occur in an exercising mammal, deterioration of performance is manifested in physical exhaustion and fatigue. Mobilization and enhancement of the KrebsHenseleit urea cycle by addition …
An Experiment On The Effects Of Humidity On Screen-Process Stencils, Thomas R. Bresadola
An Experiment On The Effects Of Humidity On Screen-Process Stencils, Thomas R. Bresadola
Electronic Theses and Dissertations
Quality control is management, it is a way of thinking. To function properly, it cannot be isolated in one section of the plant, but rather it must permeate the entire climate of the plant. Management is control through decision making. Decision making requires accurate and complete information, if errors are to be avoided. The quality of the information on which decisions are based determines the quality of the decisions themselves. Quality may be defined by stating what is acceptable, and what is not acceptable. Quality used in this sense varies greatly from plant to plant. The company printing slogans on …

Ochratoxin In Poultry Feeds : Toxic Effects On Hens, Harlal Choudhury
Ochratoxin In Poultry Feeds : Toxic Effects On Hens, Harlal Choudhury
Electronic Theses and Dissertations
Ochratoxin is a toxin produced by fungus Aspergillus ochraceus Wilh. This is one of the poisonous metabolites, like aflatoxin, which when ingested by livestock, poultry, and human beings could produce toxigenic effects—so-called mycotoxicoses. The fungus A. ochraceus is widely distributed in nature and often found in soil and vegetation. Scientists, while searching for causative agents of certain diseases not of bacterial, viral, or nutritional origin, conducted a series of experiments a few decades ago using different species of fungi grown on food and feedstuffs. Toxic effects concurrent with antimicrobial activity of certain species of molds created problems in separating one …

An Eye-Movement Analysis Of Five Ink Colors Printed On Yellow Stock, Robert Charles Clappsy
Electronic Theses and Dissertations
The use of color combinations of print and paper by commercial printers has increased steadily since 1930. The relation of color-of-print to color-of-background is an important factor to be considered in printing because color does effect legibility. The increased use of color emphasizes the need for scientific knowledge concerning the effect on legibility of various color combinations of print and background. Such scientific knowledge demands relevant research in many areas of color printing. This study will try to determine the effects on eye-movements of various ink colors printed on a controlled yellow stock. This information would be useful to printers …

Automatic Irrigation : Sensors And System, Herman G. Hamre
Electronic Theses and Dissertations
As the world in which we live becomes more crowded, the specter of food shortage looms larger. As long as the world population is increasing, the food supply must also be increased to offset predicted shortages. One area under development is the ocean, and federal money is being invested in research on ocean farming techniques. More immediate gain, however, may be obtained by bolstering the already immense capability of the agricultural community. This may be accomplished by increasing the yield of the land under cultivation, or by enabling more land to be cultivated. Irrigation has been used successfully in aiding …
Effect Of Rhythmical Disturbances On Repetitive Assembly Work, Ranganatha Hemmige
Effect Of Rhythmical Disturbances On Repetitive Assembly Work, Ranganatha Hemmige
Electronic Theses and Dissertations
The field of industrial engineering has been traditionally based on the desire to produce more goods for less money. This goal has been accomplished by a variety of methods, including improved methods, monetary incentives, and nonmonetary incentives. In the modern industry all of these may be used. Studies to isolate the effects-of such types of incentives frequently, although not exclusively, have been conducted on highly repetitive tasks. This occurs for a number of reasons: 1. The simple task reduces the variability of the output both in quality and quantity. 2. Any given number of cycles will take less time since …
The Effect Of Sodium Hexametaphosphate On The Palatability Of The Freeze-Dried Chicken, Ngoc Hoa Giang
The Effect Of Sodium Hexametaphosphate On The Palatability Of The Freeze-Dried Chicken, Ngoc Hoa Giang
Electronic Theses and Dissertations
Freeze-drying has been generally regarded as the mildest method known for drying meats, but even this process has caused undesirable changes in meat quality. The texture of rehydrated freeze-dried meat has been found to be tougher and drier than untreated meats. In addition, the meat may have a "woody" texture. Apparently something has occurred during the freeze-dry process that reduced the water-holding capacity of the meat. This has been reflected in the meat's inability to become fully rehydrated. Sodium hexametaphosphate (SHNP) has been used successfully to increase the water-holding capacity of meat and fowl. No study has been conducted to …

Flannery O'Connor And The Development Of The Grotesque In American Literature, Joan Rae Griffin
Flannery O'Connor And The Development Of The Grotesque In American Literature, Joan Rae Griffin
Electronic Theses and Dissertations
When man's view of himself as a being in his universe changes with the tide of events, literary conventions change as well. There is very little in contemporary life that would contradict the assumption that man's view of himself and of his world is no longer governed by the assurance of reason or the confidence of prediction. When certainty of man's place in the universe was commonly accepted, for instance in the eighteenth-century, this assurance was reflected in a literature which was essentially rational and ordered. In the last two centuries, drastic upheavals in the course of human events have …
Effect Of Ductility On Initiation And Spread Of Fracture In Solids, Tien Yu Hsieh
Effect Of Ductility On Initiation And Spread Of Fracture In Solids, Tien Yu Hsieh
Electronic Theses and Dissertations
The pioneer A. A. Griffith (1921), led by Inglis' idea (1913) of stress distribution around an elliptical void, set up the fundamental theory of rupture and flow in solids for the contemporary scientists in the field of fracture mechanics. Today his theory is the well known Griffith fracture criterion extensively used in investigation and explanation of fracture phenomena. Two of the recent researchers who contributed substan-tially to the field of fracture mechanics are I. N. Sneddon (1946) and R. Sack (1948). They have both derived expressions for the critical stress around a three dimensional penny-shaped crack. In addition, Sneddon found …
